The MTV Movie Awards had a clip from X-Men: Days of Future Past. It’s an early part of the movie when the “future” X-Men are stuck battling some advanced Sentinels.
This is an MTV embed, so sometimes flaky, but seems to air in the US and UK.
I spotted Iceman, Bishop, Warpath, Kitty Pryde, Sunspot and Blink. Did you notice anyone else?
